PORT ANGELES ญญ— A Clallam County Superior Court judge will be given a proposal for a mental evaluation of a Port Angeles man accused of trying to kill his 57-year-old, non-diabetic step-uncle with a potentially deadly dose of insulin.

John Hayden, with Clallam Public Defender, said in a court hearing Tuesday that he wants his client Robbie Wayne Davis, 39, to have a mental evaluation because Hayden said he has concerns over Davis' mental competency.

“I will present a [proposed] order in the next couple of days to get an evaluation done,” Hayden said.

“I think it makes sense to do that now.”

Davis was charged last week with one count each of first-degree attempted premeditated murder and first-degree assault, both with an aggravated circumstance.

Police said Davis injected Richard Haynes, who has Down syndrome, with insulin while the 57-year-old was hospitalized June 15 at Olympic Medical Center in Port Angeles.

Sheriff's Office investigators “suspected that a member of Haynes' family had administered insulin to him,” according to the Port Angeles police report filed in the attempted murder case, but were unable to develop probable cause to show that any one person was responsible for the injection based on insufficient evidence.
